SPECIFICATION forming part of Letters Patent No. 782,222, dated February14, 1905.

Application tiled August 26, 1904. Serial No. 222,214,

To 11H Vlf/mnt it Nba/y concern:

Be it known that we, GEORGE OUTIIBERT and Romeral M. SNYDnn, bothcitizens of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Turbines, of which the following is a specification.

Our invention consists of a turbine adapted to be operated by steam orother tluid, embodying' a bucketed wheel of novel construction, meansfor reversing the same, means for utilizing the exhaust fluid when inhot condition to heat feed-water, and other details, as will behereinafter set forth, the novel features being' pointed out in theclaims.

Figure l represents a vertical section on line .1^ m, Fig. 2, of aturbine embodying our invention. Fig. 2 represents a vertical sectionthereof on the line y Eig. l. Fig. 3 represents a perspective view 0f adetached portion thereof. Fig. et represents a vertical section of aportion thereof` showing the buckets of the wheel in reversed positionto that shown in Fig. 1. Eig. represents a perspective view of aportion, showing different sets of buckets, respectively, in reversedpositions. Fig. 6 represents a section of a portion of a modification.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates the easing of the turbine, and Bdesignates a wheel within tlie same whose shaft (l is properly mountedon the sidewalls (1' ofsaid casing.

l) designates buckets which are secured to the peripheral rim of thewheel l, and E designates a pluralityY of distributing-chambers on theinterior of the casing A within the buckets D, the walls F of saidchambers being somewhat angular or tangential, forming the shoulders G,in which are openings or ports occupied by the ends of the jets orjettubes H, which are thus in communication with the chambers E and leadto the inner sides of the buckets VD, with which they are incommunication, it being noted that said chambers E occupy opposite sidesofthe casing A, and they are separated by the diaphragms or divisions J,which constitute the inner walls of said chambers, the web or body ofthe wheel B occupying' the space between said diaphragms and being'rotatable therein, the chambers E thus being entirely separate from eachother and the angular' walls F extending laterally from the peripheralportions of the diaphragms J and extending concentrically,respectively.around the inner circumferenees of the buckets and close tothe same.

li designates fluid supply pipes for the chambers E, the same beingconnected with the side walls U of the casing A and being each providedwith a suitable valve L, whereby fluid may be admitted into bothchambers E or either of said chambers, as desired.

)l designates the rim of the casing (y, the same being closed, forming achamber M, which encircles the buckets l) and being adapted to receivethe exhaust steam or other fluid which leaves said buckets, a portion ofsaid rim being cut away or open, forming the exhaust passage or port N.lVithin said chamber M' is the pipe l), which in the present case is ofthe form of a coil, the same having connected therewith, respectively,the inlet-pipe Q and the outlet-pipe R,said pipe being adapted toreceive feed-water admitted through the pipe Q and discharged throughthe pipe R.

The operation is as follows: Steam, compressed air, gas, water, or otherfluid is admitted to the chamber or chambers E, and the same isdistributed forcibly by the angular or tangential walls ll toward theshoulders (l and into the jet-tubes ll, and consequently to the bucketsl), against which it is powerfully impacted, thus correspondinglyrotating the wheel B, the power being' transmitted to the shaft O andthe pulley Cl for evident purposes. 'lhe fluid after leavingthe bucketsas exhaust enters the chamber M and is carried around bythe rotationofthc rim ofI the wheel to the port N, where it escapes. lVhere the fluidemployed is hot, such as steam, the exhaust thereof acts upon the pipel?, whereby feed-water supplied to said pipe will be cf'- fectivelyheated, in which condition it is directed by the pipe R to a place ofuse. ln order to reverse the direction of rotation of the wheel, thesurface of the buckets which receive the impact of the fluid are placedin opposite directions, as in Fig. 5, whereby when fluidis admitted toeither chamber E by properly closing one of the valves L and opening theother valve L it may cause the wheel to run to the right or left, as thecase may be, the effect of which is evident. As the exhaust fluid iscarried around by the wheel in the exhaust-chamber M it is preventedfrom rentering the inoperative buckets on the other side. Owing to thewalls E, the fluid uniformlyV seeks the openings or ports in theshoulders G, and so is directed by jets or tubes H to the buckets, saidtubes flaring toward their discharge ends, whereby afull volume of thefluid may be impacted against the buckets.

Various changes may be made in the details of construction shown withoutdeparting from the general spirit of our invention, and we do not,therefore, desire to be limited in each case to the same. For instance,the rim M may be surrounded by another rim, M2, as in Fig. 6, the latterrim forming a chamber or pipe M3, which is not in communication with thechamber N it being, however. adapted to receive feed-water, which willbe heated by the exhaust or condensedfluid,whichleaves the buckets andenters said chamber M3. Again, by introducing cold water into the pipe Por chamber N 3 the iiuid leaving the buckets and entering said pipe orchamber will be condensed, thus effectively producing a vacuum whichwill cause the jets or jet-pipes to more powerfully eject the fluidagainst the buckets, whereby the turbine is more powerful in action andthe wheel will run with greater ease.

Attention is directed to the fact that the steam is not admitted to thebuckets of the wheel from the center of the latter, thus dispensing witha hollow shaft and avoiding a long passage or traverse of the steam,but, on the contrary, from the side chambers E close to said buckets, soas to be quick and effective in its action on the latter.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. A turbine consisting of a casing, a wheel having a web and aplurality of sets of buckets on the periphery thereof extendinglaterally outward therefrom in opposite directions, independentfluid-distributing chambers in in opposite directions for reversibilityand the shoulders of said walls having each therein ports leadingrespectively from the different chambers to the different sets ofbuckets.

2. A turbine consisting of a casing, a plurality of fluid-receivingchambers therein in opposite sides of said casing independent of eachother, a wheel in said casing composed of a web and a plurality of setsof peripheral buckets facing in reverse directions for reversibility andextending laterally outward from said web, said web being rotatablebetween the side walls of said chambers and a plurality ofoutwardly-extending walls concentric with the inner circumferences ofsaid buckets, shoulders on the ends of said walls and ports in saidshoulders.

3. A turbine having a casing, a plurality of independent fluid-receivingchambers in opposite sides thereof, a series of angular walls on theperipherics of said chambers, shoulders on the ends of said walls, portsin said shoulders, a wheel havinga web which is rotatable between theside diaphragms of said chambers and a plurality of sets of buckets onthe periphery of said web faced in opposite directions for reversibilityand laterally-extending shoulders onthe peripheral portions of the sidediaphragm of said chambers concentric with the inner circumferences ofsaid sets of buckets.

4. A turbine having a casing, a bucketed wheel therein, an exhaust orcondensing chamber around the buckets of said wheel and a feed-waterreceiver adapted to be heated by the exhaust or condensed fluid fromsaid buckets admitted into the chamber and exteriorly surrounding saidcondensing-chamber.

A turbine having a casing, a bucketed wheel, an exhaust-chamber and anauxiliary chamber for heating and condensing, connected with saidexhaust-'chamber and exteriorly surrounding the latter.
